Yang Guoyu was not a doctor at the health clinic.
The reason he was with Mr. Chang today was because the clinic had admitted a special patient.
Since Mr. Chang and others were unable to treat him, they had asked him to come over.

"The plan is set," said Yang Guoyu, "but to detoxify, we still lack one crucial component of the medicine."
"I know, it's just Snake Gallbladder. I have already arranged for someone to ask around at the Liu Family's place."
